Study summary

The Austrian Hypertrophic Cardiomyopathy (HCM) Registry is a prospective, multicenter registry enrolling patients at multiple outpatient clinics across Austria including academic and non-academic centers. Patients will undergo a structured examination process including assessment for symptoms of HCM, past medical history, concomitant medication, family history and the presence of HCM-specific red flags. Furthermore, clinical data derived from electrocardiogram, echocardiography, laboratory analysis, and genetic testing will be collected focusing on a lean variable dictionary and, in addition, specific hypothesis-driven research parameters. All data are entered into an electronic case report form (eCRF) (Phoenix Clinical Trial Management System). In order to perform multicenter analyses, data can be extracted from the eCRF after approval by the steering committee.

The Austrian Hypertrophic Cardiomyopathy (HCM) Registry is a prospective, multicenter registry enrolling patients at multiple outpatient clinics across Austria including academic and non-academic centers. Patients will undergo a structured examination process including assessment for symptoms of HCM, past medical history, concomitant medication, family history and the presence of HCM-specific red flags. Furthermore, clinical data derived from electrocardiogram, echocardiography, laboratory analysis, and genetic testing will be collected focusing on a lean variable dictionary and, in addition, specific hypothesis-driven research parameters. All data are entered into an electronic case report form (eCRF) (Phoenix Clinical Trial Management System). Every site will nominate one representative for the steering committee which will serve as the regulatory authority with the compentence to approve research and funding proposals.

The Austrian multicenter HCM Registry aims to facilitate a wide range of innovative cross-sectional and longitudinal epidemiological analyses unravelling gaps in evidence in HCM. The standardized clinical assessment might harmonize standards of clinical care in HCM patients in Austria.

Study population

The study population includes subjects who fulfill criteria of HCM and are treated in Austria.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients admitted to the HCM outpatient clinic of participating centers of the HCM Registry
  • Interventricular septal thickness ≥ 13 mm and cardiomyopathy-specific red flags OR Interventricular septal thickness ≥ 15 mm not explainable by loading conditions OR Interventricular septal thickness ≥ 17 mm
  • Willingness and ability to provide signed form (ICF) prior to participation in any study-related procedures

Exclusion criteria

Exclusion criteria:

  • Age \< 18 years
  • Known cardiac amyloidosis
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
